Blood test that detects changes in tumor DNA predicts survival of women with advanced breast cancer

A blood test that spots cancer-linked DNA correctly predicted that most of those patients with higher levels of the tumor markers died significantly earlier than those with lower levels, results of a multicenter study of 129 women with advanced breast cancer show.

Whole-body heat stress lowers exercise capacity, blood flow in men

Prolonged exposure to high temperatures can raise both the skin and core temperature, reducing blood flow to the brain and limbs during exercise and limiting the ability to exercise for long periods, research shows. The study is the first of its kind to separate the effects of skin- versus internal-raised temperature (hyperthermia).

Controlling electron spin makes water splitting more efficient

One of the main obstacles in the production of hydrogen through water splitting is that hydrogen peroxide is also formed, which affects the efficiency stability of the reaction and the stability of the production. Dutch and Israeli researchers from Eindhoven University of Technology and the Weizmann Institute have succeeded in controlling the spin of electrons in the reaction and thereby almost fully suppress the production of hydrogen peroxide. They published these findings this week in the Journal of the American Chemical Society. The efficient production of hydrogen paves the way towards water splitting by solar energy.

Food insecurity: A threat to the developmental and psychosocial health of children

Household food insecurity (without reliable access to a sufficient quantity of affordable, nutritious food, even for a temporary period), is associated with children's behavioral, academic and emotional problems beginning as early as infancy.

Wearable AI system can detect a conversation’s tone

Scientists have developed an artificially intelligent, wearable system that can predict if a conversation is happy, sad, or neutral based on a person's speech patterns and vitals. Coupled with audio and vital-sign data, deep-learning system could someday serve as a 'social coach' for people with anxiety or Asperger's, they say.

Targeting Parkinson’s-linked protein could neutralize two of the disease’s causes

Researchers report they have discovered how two problem proteins known to cause Parkinson's disease are chemically linked, suggesting that someday, both could be neutralized by a single drug designed to target the link.

Novel liquid crystal could triple sharpness of today’s televisions

An international team of researchers has developed a new blue-phase liquid crystal that could enable televisions, computer screens and other displays that pack more pixels into the same space while also reducing the power needed to run the device. The new liquid crystal is optimized for field-sequential color liquid crystal displays (LCDs), a promising technology for next-generation displays.
